Automatic Code completion & automatic indents [message #698367]

Hi,

recently I changed my grammar to use a code style with "if" and "endif" instead of the curly braces. I also adjusted the auto formatting to get the indent correctly if I press ctrl+shift+f.

But if I am in the editor and press enter after writing "if ..." the editor does not automatically increase the indentation as it did when I used the curly braces. How can I add this behavior again?

I also would like the editor to insert the "endif" automatically after writing the "if" line. Can this be done?

Hi,

you have to adapt the auto-edit-strategy-part of the editor. Start digging at DefaultAutoEditStrategy.

Thank you, I have implemented my own subclass of DefaultAutoEditStrategyProvider now.
Unfortunately the CompoundMultiLineTerminalsEditStrategy does not simply work for "if" and "endif" as the first is a substring of the latter, so I had to make some adjustments.

If there is a simpler way of doing this please let me know. It would be nice if those autoedit rules could be based on the grammar rules or at least on the tokens of the grammar. But I guess it is only possible to work on the character level here?
